Question

[loops] Write a java program that accepts a number, as command line argument and prints out “Hello, World!” that many times using a for loop. E.g. if the input number is 3, the program outputs:

Hello, World!

Hello, World!

Hello, World!

Keep it simple, please use the argument, not interact with the console. Thanks

code:

public class Main{
   public static void main(String[] args) {
//get command line arguments and convert it from string to integer
int n = Integer.parseInt(args[0]);
//loop n times and print hello world
for(int i=0; i<n; i++){
System.out.println("Hello, World!");
}
}
